Stromboli - effusive activity on 08.08.2019 / 08h17 GST thermal camera from Punta dei Corvi - Doc. LGS
From 18 August at 0h35 UTC, the thermal camera of Punta Dei Corvi / on Stromboli, shows the resumption of effusive activity by a probably ephemeral vent at altitude 550-600 meters, above the area of the central crater . The products issued roll along the Sciara del Fuoco.
A Modis image at 1:50 UTC records a thermal anomaly of 125 MW to 148 MW, compatible with this activity.
The explosive activity continues without significant modification.
